Jordyn Sanderson, of Portland, Mich., has been hospitalized since Wednesday when she fell 9 to 10 feet from the second-story balcony at the Sigma Pi fraternity house, at 1714 Fraternity Village Drive.

Kalamazoo Department of Public Safety investigators said Sanderson had a blood-alcohol content of 0.18 percent, more than twice the legal limit for driving, when she fell from the balcony and struck the back of her head at about 12:50 a.m. Police have said alcohol was being consumed at the party but it wasn’t yet clear whether investigators have determined if Sanderson consumed alcohol at the party.

Police said there were about 200 people attending the party and Public Safety officers were walking up to the house to break up the party at the time that Sanderson fell. Officers said they saw a large group of people standing around Sanderson when they got to the scene and Sanderson was unresponsive.

Officer have said Sanderson suffered a skull fracture in the fall and authorities believe she may have fallen through gaps between the balusters that support the balcony’s railing. The fraternity house was condemned Wednesday by city housing officials and fraternity members who lived there were ordered to leave immediately.
